PEDAL FOR AUTOMATIC PIANOS- Specification of Letters Patent.

Iatented May 21, 1907.

Application filed March 22, 1907. Serial No. 363,964.

To all whom, it may concern:

Be itknown that I, JOHN D. PEAsE, a citi zen of the United States, and aresident of the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in Pedals forAutomatic Pianos, of Which the following is a specification.

My invention relates to pedals for automatic pianos and has for itsobject to improve and simplify the construction thereof so as to makesaid pedals capable of being easily folded when not in use.

Other objects will appear from the anneXed description and the featuresof novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawing in Which Figure 1 isa side elevation of my improved construction together with as much ofthe adjacent mechanism as is necessary to illustrate my invention; andFig. 2 is a front elevation thereof.

In the drawing A represents the bellows Which may be of any customaryconstruction and are secured in position on standards or supports B soas to leave the one memberA capable of being moved in the usual manner.The supports B are secured to the base board C of the piano and arestrengthened by means of braces D having their one end fastened to astationary portionE of the piano. F is the usual spring located. betweensaid stationary portion E and the movable portion A of the bellows A forthe purpose of returning said movable portion to its normal position.

G are the pedals which are provided at the heel ends with lugs IIpivoted by means of a rod I to lugs forming part of or secured to thecross bar K, to which are secured standards or feet L. Rods M aresecured to the cross bar K near each end thereof and each rod has itsother end pivotally secured at M to the supports B. The pedals G areeach further provided at the toe ends with lugs or ears 0 to which aresecured links P which in turn are pivotally fastened at P to arms Q.These arms Q are fastened by means of nuts Q to the movable member A ofthe bellows A. Rollers R are journaled on the pedals G and are arrangedto engage guides or cams S secured to the supports B for the purpose tobe more clearly described hereinafter.

T is a catch or lock located on a stationary portion of the bellows andis adapted to engage the cross bar K for maintaining said pedals intheir folded position.

In the drawings the pedals are shown in the operative or playingposition, that is they are in a position to work the bellows to operatethe piano. hen the pedals are no longer required and it is desired tofold them into the case, the heel ends G are lifted upward by pressingagainst the cross bar K. This will cause the rollers R to ride on thecams S thus forcing the ends G of the pedals G downward. During thisoperation the rods M will swing on their pivots M until the pedals havebeen swung inward and the ends G thereof have been caught under thecatches T. The links P meanwhile swing on the pivot P it beingunderstood that as the ends G of the pedals move downward the arms Q areforced back with the movable portion A of the bellows. The pedals maythus be easily lifted into a folded or inoperative position by the footof the user thus doing away with the necessity of bending down on thepart of the person using the instrument. My construction also permitsthe pedals with their connections to be completely folded out of theway.

- Various modifications may be madewithout departing from the nature ofmy inven tion as defined in the claims.

I claim 1. The combination of the bellows having a forwardly projectingarm secured to its movable member, the link pivoted to the forward endof said arm, the pedal the toe end of which is pivotally connected withthe other end of the link, the rod one end of which is fulcrumed on astationary support and the other end of which is pivotally connectedwith the heel end of the pedal, the cam or guide for the toe end of thepedal, and means for holding the pedal in its elevated position.

2. The combination of two bellows each having a forwardly-projecting armsecured to its movable member, the links pivoted to the forward ends ofsaid arms, the pedals having their toe ends pivotally connected withsaid links, cams or guides for the toe ends of the pedals, rodsfulcrumed on a stationary support, a crossbar connecting said. rods andpivotally connected with the heel ends of the pedals, and means forholding the pedals in their elevated position.

3. The combination of two bellows, each having a forwardly-projectingarm secured to its movable member, the links pivoted to the forward endsof said arms, the pedals having their toe ends pivotally connected withsaid links, cams or guides for the toe ends of the pedals, rodsfulcrumed on a stationary support, a crossbar connecting said rods andpivotally connected with the heel ends of the pedals, feet dependingfrom said crossbar, and means for holding the pedals in their elevatedposition.

4. The combination of the bellows, the pedal, the link pivotallyconnected with the movable member of the bellows and with the toe end ofthe pedal, the rod one end of which is fulcrumed on a stationary supportand the other end of which is pivotally connected with the heel end ofthe pedal, and the cam or guide for the toe end of the pedal.

5. The combination of the bellows, the pedal, the link pivotallyconnected with the movable member of the bellows and with the toe end ofthe pedal, the rod one end of which is fulcrumed on a stationary supportand the other end of which is pivotally connected with the heel end ofthe pedal, the cam or guide for the toe end of the pedal and means forholding the pedal in its elevated position.

6. The combination of the bellows, the pedal, an operative connectionbetween the pedal and the bellows, a normally stationary memberconnected with the pedal to move therewith when the pedal is beingshifted to its inactive position, and a guide for directing the toe endof the pedal during such shifting movement.

7. The combination of the bellows, the pedal, an operative connectionbetween the pedal and the bellows, a normally stationary memberconnected with the pedal to move therewith when the pedal is beingshifted to its inactive position, a guide located adjacent to the pathwhich the toe end of the pedal describes during such shifting movement,

and a roller carried by the toe end of the pedal and engaging saidguide.

8. The combination of the bellows having a forwardly projecting armsecured to its movable member, the link pivoted to the forward end ofsaid arm, the pedal, the toe end of which is pivotally connected withthe other end of the link, the red one end of which is fulcrumed on astationary support and the other end of which is pivotally connectedwith the heel end. of the pedal, and the cam or guide for engaging thetoe end of the pedal as the latter is being shifted to its inactiveposition.

9. The combination of two bellows each having a forwardly-projecting armsecured to its movable member, the links pivoted to the forward ends ofsaid arms, the pedals having their toe ends pivotally connected withsaid links, cams or guides for engaging the toe ends of the pedals asthe latter are being shifted to their inactive position, rods fulcrumedon a stationary support, and a crossbar connecting said rods and pivotally connected with the heel ends of the pedals.

10. The combination of two bellows each having a forwardly-projectingarm secured to its movable member, the links pivoted to the forward endsof said arms, the pedals having their toe ends pivotally connected withsaid links, cams or guides for engaging the toe ends of the pedals asthe latter are being shifted to their inactive position, rods fulcrumedon a stationary support, a crossbar connecting said rods and pivotallyconnected with the heel ends of the pedals, and feet depending from saidcrossbar.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
